Data center NVIDIA and Mediatek Ink $3.5B Investment Deal, Accelerate NVLink Fusion Adoption
Under the terms of the deal, NVIDIA is investing $3.5B in MediaTek by purchasing convertible bonds issued by the company. Meanwhile, on the technology side of matters, MediaTek will be adopting NVIDIA’s complete NVLink Fusion technology stack, the Fusion chiplet, NVLink-C2C, and NVIDIA’s new NVHBM memory protocol, in order to provide it to its own customers. The significance of this technology licensing is that, as MediaTek’s custom silicon business has grown, NVIDIA wants to make its IP readily available to MediaTek’s customers, particularly those working with MediaTek to develop their own XPU accelerator chips.
The most significant element of this technology offering is the NVLink Fusion chiplet, which NVIDIA has offered since last year. The fabric bridge chip allows chip designers to integrate NVLink support via a UCIe-attached chiplet that provides full-chip NVLink fabric support (while keeping the central components of NVLink as a black box to be integrated rather than licensing the IP itself). This is the critical part to enabling NVLink support on custom XPUs, and allowing those chips to plug into NVLink networks and NVIDIA’s rackscale hardware ecosystem.
Looks like Nvidia wants to make sure that even if hyperscalers go with custom silicon that it can still exist in an Nvidia rack platform. They have a similar platform inclusion with Marvell and Amazon. No Broadcom though. I wonder if AMD gets an invite. ;-)

The platform bundles the technologies that surround a custom XPU: the NVLink Fusion Chiplet, which connects XPUs to Nvidia's NVLink scale-up fabric over photonic or electrical interconnects; NVLink-C2C, providing high-bandwidth links between XPUs, Nvidia Rosa CPUs and other compatible processors; and NVHBM, which integrates customized memory to raise bandwidth and efficiency while freeing silicon area for compute.
Under this arrangement, customers bring their XPU designs to MediaTek and tune connectivity, memory, packaging, performance and power to their workloads, while Nvidia and MediaTek carry the surrounding stack — including the MGX rack-scale architecture.
